MARTIN P. VAN RYZIN, OF APPLETON, WISCONSIN.

PAPER-STOCK-REFINING ENGINE.

SPECIFICATION formingpart of Letters Patent No. 653,856, dated July 17, 1900.

Application filed April 16, 1900.

To all whom it may concern:

Be it known that I, MARTIN P. VAN Rvznv, a citizen of the United States, and a resident of Appleton, in the county of Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Paper-Stock-Refining Engines; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to simplify and cheapen manufacture of the conical cores pertaining to What is commonly known as Jordan type engines for refining paperstock and also to facilitate setting and removal of the knives employed in connection with said cores.

Therefore said invention consists in certain peculiarities of construction and combination of parts herein particularly set forth with reference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawings represents a longitudinal section of a portion of my improved core for a Jordan type paper-stock-refining engine, a rib and knives appearing in this view being broken; Fig. 2, a transverse section of the core with ribs, knives, and spacers thereon; Fig. 3, a plan view of said ribs,knives, and spacers on the core; Fig. 4, a perspective view of part'of one form of spacer; Fig. 5, a similar view of another form of spacer; Fig. 6, a perspective view of one of the knives, and Fig. 7 a like view of part of one of the ribs.

Referring by letter to the drawings, A indicates a cast-iron conical core fora Jordan type paper-stock-refining engine, and in accordance with myinvention bands B are made fast on the c0re,at intervals thereof,by shrinking or otherwise, these bands being machined to form annular recesses next the core-face. As herein shown, the bands may be provided at intervals with notches for engagement of ribs 0, the number and arrangement of these ribs being a matter of arbitrary selection. The ribs are preferably metal, outwardly channeled, and held to the cylinder by machine-screws D, the heads of which are sunk within the channels. It is preferable to have Serial No. 13,029. (No model!) the rib-channels filled with Wood or other suitable material E, as herein shown.

Alternately disposed between ribs C are knives Fand wooden spacers, all of the knives being notched at their ends to fit in under and preferably over the flanges that result from recessing the bands on the aforesaid core. It is herein shown that spacer G is made dif-' ferent from the other spacers G of a series in that its ends are not made like the ends of the knives to fit in recesses of the adjacent cone-bands, but to be driven in between said cone-bands and serve as a key by which said other spacers and knives are held in place. However, all of the spacers may be made similar to the one G, if desirable.

From the foregoing it will be understood that the knives F and spacers may be readily assembled and firmly held in place on the conical core by the wedging action of said spacers. It is also obvious that if a spacer be withdrawn the other spacers and the knives may be readily removed.

While I have shown the assembled ribs, knives, and spacers parallel with the conical core, they may be set at an angle to said core, if desired, and the number of said knives in any series is optional.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The core of a paper-stock-refining engine provided with annularly-recessed bands at intervals of its length, ribs arranged longitudinally of said core between bands thereon, knives having notched ends fitting the bandrecesses, and spacers confining the knives in series between core-ribs.

2. The core of a paper-stock-refining engine provided with annular bands at intervals of its length recessed to form flanges, ribs arranged longitudinally of said core between bands thereon, knives having notched ends fitting under and over flanges resulting from recessing of said bands, and spacers locking the knives in series between core-ribs.

3. The core of a paper-stock-refining engine provided with annularly-recessed bands at intervals of its length, outwardlychanneled ribs arranged longitudinally of said core between bands thereon, screws connecting the ribs and core, the heads of the screws being within ribchannels, fillers for said rib-channels, knives 5 having notched ends engaging the bands between ribs on said core, and spacers locking the knives in series between core-ribs.

4. The core of a paper-stock-refining engine, bands shrunk on the core at intervals of its 10 length and annnlarly recessed adjacent to said core, ribs on the aforesaid core longitudinally of the same between bands thereon,

knives notched at their ends to engage the recessed bands, and spacers lockin g the knives in series between core-ribs.

In testimony that I claim the foregoing I have hereunto set my hand, at Appleton, in 1 the county of Outagamie and State of Wisconsin, in the presence of two witnesses.
